DynamoDB

Overview

• Fully Managed Highly available with replication across 3 AZ

• NoSQL database - not a relational database

• Scales to massive workloads, distributed “serverless” database

• Millions of requests per second, trillions of rows, 100s of TB of storage

• Fast and consistent in performance

• Single-digit millisecond latency – low latency retrieval

• Integrated with IAM for security, authorization and administration

• Low cost and auto-scaling capabilities

• Standard & Infrequent Access (IA) Table Class

Type of data

• DynamoDB is a key/value database

Accelerator - DAX

  • Fully Managed in-memory cache for DynamoDB

  • 10x performance improvement – single- digit millisecond latency to microseconds latency – when accessing your DynamoDB tables

  • Secure, highly scalable & highly available

  • The difference with ElastiCache at the CCP level: DAX is only used for and is integrated with DynamoDB, while ElastiCache can be used for other databases

Global Tables

• Make a DynamoDB table accessible with low latency in multiple regions

• Active-Active replication (read/write to any AWS Region)
